DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings, the apparatus for the construction and assembly of prefabricated building sections or room units comprises a frame generally indi' cated by the reference numeral I which frame includes upright side frames 2 and 3 disposed towards the opposite lateral sides of the apparatus. Each of the two side frames 2 and 3 comprises a plurality of vertical beams 4 that are interconnected at various levels by horizontal beams 5. The side frame 2 is provided with a platform 6 that is located at a level substantially midway between the top and the bottom of the apparatus and, similarly, the side frame 3 is provided with a platform 9 disposed at the same level as the platform 6. The platform 9 has a greater lateral width than the platform 6, the width of the wider platform 9 being equal to the approximately two-thirds of the distance 28 that separates the two side frames 2 and 3. The opposite ends of the platform 6 are provided with flights of steps 7 and 8 giving access to and from ground or floor level and the op posite ends of the platform 9 are provided with similar flights of steps 10 and 11 for the same purpose. The tops of the two side frames 2 and 3 are interconnected adjacent the front of the apparatus by a frame of horizontal beams 12 that together afford a bridge 13. Flights of steps 14 and 15 provide access to the bridge 13 from the platforms 6 and 9 respectively. The tops of the two side frames 2 and 3 are also interconnected adjacent the rear of the apparatus by a frame of substantially horizontal beams 16 that together afford a platform 17. Flights of steps 18 and 19 give access to the platform 17 from the platforms 6 and 9 respectively. The bridge 13 and platform 17 are located at a vertical height 32 above ground or floor level of 3.2 meters.

The side frames 2 and 3 are also interconnected ad jacent the rear of the apparatus by a few substantially horizontal beams that together afford a bridge 20 which is disposed beneath the platform 17 at a height above the ground or floor which is slightly less than half the height 32 of the platform 17. A similar bridge or platform 23 is disposed near the front of the apparatus beneath the bridge 13 at the same height above the ground or floor as the bridge 20. However, as can be seen in FIG. 1 of the drawings, the bridge or platform 23 is carried by a support 24 so as to be longitudinally displaceable (i.e. laterally of the apparatus) between the positions thereof that are shown in full and broken lines in FIG. 1. Flights of steps 26 and 27 give access from the ground or floor to the bridge or platform 23 in the region of the support 24 and to that ends 25 of the bridge or platform 23 which will be farthest remote from the support 24 when the bridge or platform occupies the position thereof that is shown in full lines in FIG. 1. Further flights of steps (not shown) that are similar to the steps 26 and 27 provide access between the ground or floor and the opposite ends of the bridge 20 that is located adjacent the rear of the apparatus.

The apparatus includes longitudinally extending and relatively parallel supports in the form of substantially horizontal rails 30 and 31 that are spaced apart from one another by a horizontal distance 33 of substantially 250 centimeters. The side frames 2 and 3 are anchored to the ground or to a floor at horizontal distances 34 and 35 from the rails 31 and 30 respectively, the distances 34 and 35 being equal and of fixed magnitude due to the rails 30 and 31 also being anchored to the ground or to the same floor as the side frames 2 and 3. As seen in plan (FIG. 2), the frame 1 is of oblong configuration and bears against the ground surface or floor by way of the longer sides of the oblong which longer sides are afforded primarily by the two side frames 2 and 3 that extend parallel to the rails 30 and 31. The shorter sides of the oblong that interconnect the side frames 2 and 3 are afforded principally by parts that are spaced from the ground surface or floor. The side frames 2 and 3, the bridge 13 and the platform 17 together enclose a central region of the apparatus that is open at the top inside which region assembly of prefabricated box-shaped building sections or room units can be undertaken. The side frames 2 and 3 are interconnccted at the rear of the apparatus by supports in the form of both the upper platform 17 and the underlying bridge 20 whereas. adjacent the front of the apparatus,

the side frames are interconnected only by a support in the form of the bridge 13. It will be seen from FIG. 2 of the drawings that the rails 30 and 31 extend beyond the apparatus at both the shorter sides thereof, those portions of the rails 30 and 31 that are inside the frame 1 constituting, however, part of the apparatus itself.

Vertical beams 40, 41, 42 and 43 are provided adjacent the opposite ends of the side frames 2 and 3, said beams 40 to 43 forming supports for stops, arrangements for which are shown in the drawings only in relation to the stops that are associated with the beam 40. The stops that are associated with the other beams 41 to 43 are arranged in a similar, or symmetrically similar. manner. A floor stop 44 (FIGS. 1, 3 and 4) is ar ranged close to the foot of the beam 40 so as to be pivotable about a vertical pin or shaft 45. Such pivotal movements are effected by the operation ofa hydraulic piston and cylinder assembly 46, the piston rod of which is pivotally connected to the stop 44 and whose cylinder is connected by a pivot 47 to a bracket on the side frame 2. The beam 40 is provided, at a level above that of the floor stop 44, with four side wall stops 48, 49. 50 and These side wall stops 48 to 51 are arranged in pairs towards the upper and lower ends of the beam 40 as can be seen best in FIG. 3 of the drawingsv The four side wall stops 48 to 51 are coupled together by a connecting beam 52 which projects upwardly beyond the uppermost flat plate-shaped stop SI through a distance 53 (FIG. 3). The beam 52 is pivotally connected to the piston of a hydraulic piston and cylinder assembly 54 at substantially the level of the platform 6, the opposite end 55 of the assembly 54 being turnable about a substantially vertical pivot 56 (FIG. 5) relative to the side frame 2. The two pairs of side wall stops 48/49 and 50/51 are turnable relative to horizontal lugs 59 and 60 carried by the beam 40 about substantially vertically aligned pivot pins 57 and 58. The beam 40 is provided, close to the floor stop 44, with a projecting lug 61 (FIG. 4) and with further lugs 62 that are located close to the two pairs of stops 48/49 and 50/51. The free ends of the lugs 61 and 62 carry microswitches 63 and 64 respectively or alternative mechanisms designed to sense, and thus be capable of indicating, contact. As previously mentioned. the stops associated with the three beams 41, 42 and 43 are indentical, or symmetrically identical, with those that have been described in association with the beam 40 and the same reference numerals are therefore used to indicate all of them throughout the drawings.

A bearing 65 (FIG. 5) is provided at the upper end of the beam 52 and a roof stop 66 is carried by that bearing. A lug 67 projects horizontally outwardly from the lower end of the bearing 65 and its outer end is pivotally connected to the piston rod of a hydraulic piston and cylinder assembly 68, the cylinder of which, in turn, is pivotally connected to a lug 69 forming part of the side wall stop 51. A side wa l or facade support 80 is arranged close to the side frame 2 towards one of the longer sides of the apparatus and a further side wall or facade support 81 is substantially symmetrically arranged close to the side frame 3 towards the opposite side of the apparatus. Since the two supports 80 and 81 are substantially symmetrically identical, it is only necessary to describe the side wall support 80 in detail. The support 80 has a length 82 (FIG. 2) which is only marginally less than the length of one side of the apparatus, the support 80 being pivotally connected to ground or floor anchorages 84 (FIG. 6) at a plurality of locations along its length by corresponding substantially horizontally aligned pivot pins 83. The anchorages 84 are rigidly connected to the rail 31. The side wall support has a frame which comprises generally upright beams 85, the lowermost ends of which are connected to the anchorages 84 by the pivot pins 83. The upper ends of the beams 85 are interconnected by a substantially horizontal beam 86 of oblong crosssection. The beam 86 is pivotally connected to the piston rods of two hydraulic piston and cylinder assemblies 87 which latter are spaced apart from one another by a considerable distance along the length of the beam 86. The cylinders of the assemblies 87 are pivotally connected by horizontal pins 88 to a horizontal beam 89 that is rigidly fastened to the side frame 2. The assemblies 87 are so constructed and arranged that the top of the side wall support 80 is adequately and uniformly sustained thereby. The side of the support 80 which faces the support 81 is provided with a stop 90 in the form of one or more flat plates backed by relatively perpendicular stiffening ribs 9|. The ribs 91 are fastened to the upright beams 85 by bolts 92 and it will be seen from FIG. 6 of the drawings that the ribs are formed with at least two holes 93 for alternative cooperation with the various bolts 92 so that the stop shall be capable of occupying at least two different fixed positions relative to the beams 85. The tops of the stiffening ribs 91 are formed as guide arms 94 (FIGS. 2 and 6) having downwardly inclined surfaces 95 whose lowermost ends make junctions with the operative surface 96 of the stop 90 itself.

Further partition or wall stops 100 are provided beneath the stop 90 and are pivotally connected to the beams 85 by horizontal pivot pins 101 although it is noted that it is also possible to provide additional stops 100 at locations between the beams 85. The stops 100 project away from their pivot pins I01 through a distance I02 (FIG. 6) which is approximately twice the distance 103 by which the pivot pins 83 are spaced from the rail 31. As can be seen in FIG. 3 of the drawings, each stop 100 includes two arms 104 and 105 that are horizontally spaced apart from one another by a distance I06 that preferably has the same magnitude as the thickness of the building section or room unit walls or partitions that are to be assembled. The distance 106 may, for example, be I 1 centimeters but other values can be substituted when required. Each of the stops 100 is provided with a corresponding adjusting or operating lever 107 by which it can be turned about the corresponding pin 101 for retention in any chosen one of at least two different angular settings about that pivot pin. In the angular setting that is shown at the righthand side of FIG. 6, the stops 100 project substantially perpendicularly from the general plane of the side wall support 80 whereas, in an alternative position, that is shown at the left-hand side of FIG. 6, the stops 100 are inclined at only a few degrees to the beams 85 and to the general plane of the side wall support 81. In the last-mentioned positions of the stops 100, the levers 107 extend very approximately perpendicular to the general plane of the corresponding side wall support whereas, in the first-mentioned position illustrated at the right-hand side of FIG. 6, the levers 107 are substantially parallel to the general plane of the corre sponding side wall support. In the apparatus which is being described by way of example. each of the two side wall supports 80 and 81 has seven of the partition or wall stops 100 (see FIG. 2) which stops are spaced apart from one another by differing distances 110, 111 and 112. It is noted that a different number of the stops 100 may be provided if desired and that the distances 110 to 112 may be greater or smaller than those shown in FIG. 2.

The tops of both of the side frames 2 and 3 have stop arms 116 connected to them by horizontal pivot pins 118. The ends of the stop arms 116 that are remote from the pins 118 carry generally U-shaped stops 117 which are so constructed that the distance between the limbs of each stop 117 is the same as the distance 106 (FIG. 3). A horizontal frame beam 120 of rectangular cross-section interconnects the tops of the beams 4 of the side frame 2 and has an upper corner 119 (FIG. 6) that forms a restraining abutment for the arms 116. If desired, cams or other members may be secured to the beam 120 for adjustable co-operation with the arms 116. The rails 30 and 31 are provided with flanged roller 121 and 122 that are freely rotatable about horizontal axle pins 123 and 124.

The apparatus which has been described may be employed for the simple and rapid assembly of building sections or room units from prefabricated panels. A section or room unit will usually comprise panels affording a floor, walls and a ceiling and/or roof and the apparatus which has been described is employed in rapidly and correctly bringing these panels to their proper relative positions at which time they are permanently secured to one another by, for example, welding together skeletal metal beams thereof. FIG. 9 of the drawings illustrates a typical example of one boxshaped building section or room unit that can be assembled in apparatus in accordance with the invention. The section or room unit shown in FIG. 9 has the general shape of a rectangular parallelepiped and comprises a floor 131, an outer side wall 132 at one short end, upright skeletal beams 133 at the opposite short end, an internal partition wall 134 and a portion 134A of an external wall or facade that is located at one longer side of the section or unit. A top panel 135 is also provided and this top panel may be furnished with a ceiling on its lower surface and with a floor or roof on its upper surface as appropriate to the prefabricated building of which the section or room unit is intended to form a part. Clearly, if the section or room unit is to be part of a single story building or is to form, or be part of, the upper story of a building, then the upper surface of the panel 135 will need to be provided with a roof. The apparatus which has been described will normally be located on a factory floor and the various prefabricated panels can conveniently be introduced downwardly into the apparatus in substantially vertical dispositions (when required) through the open central region of the apparatus from a traveling crane movable along a track extending over the apparatus. The prefabricated panels may conveniently be made in the same factory and be stored at a location which is also accessible to the travelling crane.

In the assembly of a building section or room unit in the apparatus which has been described, a floor panel, such as the panel 136 shown in FIG. 6, is lowered through the open central region of the apparatus onto the rollers 121 and 122 of the rails 30 and 31 by, for example, a crane-operated hoist 70 of the kind shown in FIGS. 1 to 3 of the drawings. The floor panel 136 is afforded by a rectangular framework of beams 137 and 138 between which a concrete slab 139 has been cast. As shown in FIG. 6 of the drawings. the lower flanges of the beams 137 and 138 are free of the concrete slab 139 and rest on the rollers 121 and 122 between the opposed flanges thereof. The four floor stops 44 that are associated with the corresponding four beams 40, 41, 42 and 43 are employed to arrange and maintain the floor panel 136 in its correct position on the rails 30 and 31 during the assembly of the building section or room unit and, to this end, the piston rods of the assemblies 46 are extended to turn the stops 44 about the pins or shafts once the panel 136 has been placed in an initial approximately correct position on the rails 30 and 31. The stops 44 are thus brought from the posi tion thereof that is shown in respect of one of them in broken lines in FIG. 4 of the drawings to the position thereof that is shown in full lines in the same Figure in which latter position relatively perpendicular guide sides or edges 140 and 141 engage a corner ofthe panel 136, the four stops 44 acting in unison to bring the panel to exactly its appointed position on the rails 30 and 31. The stops 44 subsequently serve as locking members to hold the floor panel 136 in that position while the further steps in the assembly take place.

Wall panels such as those constituting the outer side wall 132, the internal partition wall 134 and the facade or outer wall portion 134A are next placed in their correct positions on the floor panel 136 using the side wall stops 48, 49, and 51. These stops 48 to 51 are first retracted by the assemblies 54 to the positions thereof that are shown in respect of one of them in broken lines in FIG. 5 and the panels are then lowered into the open central region of the apparatus by the co-operating overhead travelling crane, said panels occupying sub stantially vertical positions. When the panels are in approximately their correct positions, the assemblies 54 are operated to bring the stops 48 to 51 to positions corresponding to the position that is shown in full lines in respect ofthe stop 51 in FIG. 5. Each of the stops has two relatively perpendicular sides or edges 142 and 143 and these sides or edges contact the outer surfaces and edges of the wall panels concerned urging them into exactly correct positions. FIG. 6 of the drawings shows the panel that affords the internal partition wall 134 occupying an upright position on the floor panel 136 after it has been lowered into that position by the travelling crane. The panel is located between the limbs of two opposite stops 100 that are connected to the opposed side wall or facade supports and 81. The uppermost edge of the panel affording the partition wall 134 is engaged and held by two of the U-shaped stops 117 although it is noted that FIG. 6 of the drawings does not show the left-hand stop 117 in its operative position but in a withdrawn inoperative position. The distance 106 (FIG. 3) and the equal distance between the limbs of each stop 117 is, of course, chosen to fit the thickness of the panel affording the partition wall 134 and said panel is thus both located and subsequently maintained in exactly its correct disposition in the building section or room unit that is being assembled. It should be noted that, although not illustrated in the accompanying drawings, additional generally U-shaped stops 117 may be provided for co-operation with the tops of end wall panels such as the panel that affords the outer side wall 132 in FIG. 9. The stops are preferably provided with adjustable means (not shown) for moving panels such as that affording the partition wall 134 laterally across the floor panel 136 in order to be able to position such panels in a laterally correct manner as well as a longitudinally correct manner with regard to the length of the apparatus and the building section or room unit that is being formed therein. Once a correct position of the various wall panels has been attained by the use of the stops, those panels are permanently secured to the floor panel 136 by, for example, welding. The wall panels will normally incorporate vertically dis posed metal beams and the lowermost ends of those beams can readily be welded to, for example, the horizontal beams 137 and 138 of the floor panel 136 that can be seen in FIG. 6 of the drawings.

When a building section or room unit is to include external or internal walls along one or both of its longer sides, then the prefabricated panels affording such walls are brought to their correct assembly positions by employing the side wall or facade support 80 and 81. The left-hand side of FIG. 6 and the whole of FIG. 7 of the drawings illustrate the positioning of an internal partition wall panel 150 at one longer side of a section or room unit that is being assembled. The panel 150 is lowered into the open central region of the apparatus by the aforementioned co-operating overhead crane and, during such lowering, it is directed into approximately its correct position by hearing against the inclined surface 95 of at least one, and preferably at least two. of the guide arms 94. The partition or wall stops 100 are arranged in the upwardly tilted inoperative positions shown at the left-hand side of FIG. 6 and in FIG. 7 at this time so that the stops 100 can in no way impede the correct positioning of the panel 150. Stops, which are preferably adjustable but which are not shown in the drawings, are provided for moving panels such as the panel 150 to their correct position lengthwise of the apparatus (i.e. in a direction perpendicular to the plane of FIG. 6), such stops being connected to the supports 80 and 81. Once the correct longitudinal position of a panel, such as the panel 150, has been attained by the use of the stops which have just been mentioned, the support 81 is turned about the pivot pins 83 at its foot by operation of the corresponding pair of piston and cylinder assemblies 87, such opereration bringing the support 81 and the panel I50 from the positions thereof that are shown at the left-hand side of FIG. 6 to the positions illustrated in FIG. 7. The panel I50 will then occupy exactly its correct position in the section or room unit under assembly in longitudinal, lateral and vertical directions. Vertical beams of the skeleton of the panel 150 can then be secured to at least one horizontal beam, such as the beam I37, of the floor panel 136. Further welded connections can, if considered necessary, be established between vertical skeletal beams of the panel 150 and similar beams of the panels affording the outer side wall 132 and the in ternal partition wall 134.

If one of the longer sides of a section or room unit under assembly has to be provided with at least one wall panel which is to form part of an outer wall of the eventual building, then such panel will normally have a greater thickness than the thickness 151 (FIG. 6) of the panel 150. FIG. 8 shows such an outer wall panel 153 whose thickness I54 is appreciably greater in magnitude than the thickness 151. In order to be able to use the same side wall supports 80 and 81 for the correct positioning of thicker panels, such as the panel I53, the

previously mentioned alternative holes 93 are employed for co-operation with the bolts 92 to fasten the ribs 91 to the upright beams 85. The supports and 81 are thus adjustably mounted in the apparatus and it will be noted that it is, of course, possible to provide more than two holes 93 in each set thereof so that said supports 80 and 81 can be used correctly with panels of more than two different thicknesses. Once the bolts 92 have been entered through the correct holes 93 for co-operation of the supports 80 or 81 or both with at least one thicker panel, such as the panel 153, such panel is brought to exactly its correct appointed position in the same way as has been described with reference to FIGS. 6 and 7 of the drawings in respect of the thinner internal partition wall panel 150. Securing of each such panel to the floor panel 136 and, where required, to further internal partition wall panels, is also effected, preferably by welding, in the manner that has previously been described.

Once all of the internal partition walls and external walls are permanently secured in their appointed positions on the floor panel 136, the top panel I35 that is shown in FIGS. 1, 3 and 9 of the drawings is placed in its correct position to complete the basic structure of the building section or room unit. The hoist I70 is employed to bring the top panel to approximately its correct position in a substantially horizontal disposition and, subsequently, the roof stops 66 are used for the final correct positioning operation. The top panel 135 is afforded principally by a concrete slab that closes the top of all or part of the corresponding section or room unit and, if an overlying roof is necessary, it can be arranged on the upper surface of the panel 135. It is not always necessary to provide the lower surface thereof with ceiling material such as ceiling tiles. The stops 66 are brought into operation by the hydraulic piston and cylinder assemblies 68 which move them from the inoperative position shown in broken lines in respect of one of them in FIG. 5 to operative positions corresponding to the full line position that is illustrated in FIG. 5 in respect of the same stop. Relatively perpendicular sides or edges and 156 co-operate with the corners of the panel 135 and bring that panel to exactly its correct assembly position. The panel 135 preferably includes a skeleton of metal beams and these beams are welded, or otherwise rigidly secured, to the upper ends of skeletal beams of the various internal partition wall panels and external wall panels.

It will be apparent from the preceding description and from the accompanying drawings that the various prefabricated panels that are employed to form the floor, walls and ceiling and/or roof of a building section or room unit can all be introduced into the apparatus through the open top of its central region by employing a co-operating overhead travelling crane or other appropriate hoisting gear, the apparatus preferably being located in the same factory as that in which the panels themselves are formed. The described and illustrated apparatus very greatly facilitates bringing the panels quickly and easily to their appointed positions in which they can be maintained during their permanent interconnection to form the basic structure of a building section or room unit. The various platforms and bridges ofthe apparatus can be used during the positioning and interconnection of the panels and thus effectively afford working floors. When a section or room unit has been completed in the apparatus, the floor stops 44 are brought to the inoperative broken line positions thereof shown in FIG. 4, the side wall stops 48 to 51 and the roof stops 66 are brought to the broken line positions shown in FIG. by retracting the piston and cylinder assemblies 54 and the supports 80 and 81 are moved to the inclined positions thereof that are shown in respect of the support 81 at the left-hand side of FIG. 6. It should be noted that the piston and cylinder assemblies 54 move the stops 66 as well as the stops 48 to 51 be cause the stops 66 are pivotally mounted on the beams 52 and those beams are bodily displaced about the axes of the pivot pins 57 and 58 upon operating the assemblies 54. The levers I07 are operated to bring the stops 100 to the retracted inoperative positions thereof that are shown at the left-hand side of FIG. 6 and in FIG. 7. The stops 117 are also brought to the inoperative positions thereof that are shown at the left-hand side of FIG. 6 and in FIG. 7 and the basically completed build ing section or room unit is then left supported only from beneath by the rails 30 and 31. Upon moving the bridge 23 to the retracted position thereof that is shown at the left-hand side of FIG. 1 in broken lines, the front of the apparatus is completely opened and the completed section or room unit can be moved slowly out of the front of the apparatus along the rails 30 and 31 preferably by employing a travelling chain in the manner indicated in outline in FIGS. 1 and 2. It will be realized that the height 32 of the bridge 13 above the ground or floor level is such that the completed building section or room unit will pass beneath it with ample clearance.

The various stops that have been described may all be provided with sensing means such as the microswitches 63 and 64 that are shown in FIGS. 4 and 5 of the drawings and these microswitches or other sensing means may be connected to indicating means, such as electric lamps, carried by a control panel 161 (FIG. I). The indicating means on the control panel 161 will thus show whether or not the various panels and stops have reached their correct relative positions. The various stops and side wall or facade supports that have been described may have different shapes to enable them to be used for the assembly of other building sections or room units but the various hydraulic piston and cylinder assemblies by which they are operated are preferably all controlled from a single point which, in the embodiment that is being described, is a control panel 162 (FIGS. 1 and 3) that is located at the front of the apparatus at ground or floor level. The control panel 162 may, in addition to its controls, be provided with indicating means such as electric lamps or the like that are also connected to the microswitches 63 and 64 or other sensing means. It can then be seen on the control panel 162 whether the operation of different controls has produced the required result or whether some manual assistance is required. If desired, the two control panels 16] and 162 may be similar to one another and may be arranged for alternative employment so that the operation of the apparatus can be controlled and supervised at either chosen panel. The stops 100 that are carried by the side wall support 80 and 81 are arranged at different points so that they may be used, as required, for the assembly of differing sections and room units in which. for example. internal partition walls occupy various locations lengthwise of such sections or units.

FIG. diagrammatically illustrates the construction of a building in the form of a bungalow formed from five juxtaposed building sections or room units I65, I66, 167, 168 and 169. The section or room unit substantially corresponds to the one that is illustrated in FIG. 9. It can be seen from FIG. I0 of the drawings that, whereas all five of the sections or room units are of substantially the same overall dimensions, the number and arrangement of internal partition walls varies considerably from one section or unit to another. The apparatus is provided with the necessary complement of appropriately positioned stops so that all of the different sections or room units 165 to I69 can be assembled therein without major re-arrangement of the apparatus If desired. the apparatus may be employed in providing at least internal partition walls of some sections or room units with finishes during the presence of the corresponding panels in the apparatus. For example, wall tiles and the like may be fastened to internal partition walls where required. Guide marks can be provided in the apparatus to indicate the correct locations of wall tiles or other wall coverings so that operators installing such tiles or other coverings shall be assisted in their work to the greatest possible extent. It has already been mentioned that the various stops can have different shapes to those illustrated or may be replaced by alternative stops of completely different forms for co-operation with prefabricated panels of different shapes. The bridges 20 has been described as being a stationary bridge but, if desired, it may be laterally displaceable in the same manner as the bridge or platform 23 so that basically completed building sections or room units can be removed from the apparatus through either the frat or the rear thereof.

Although certain features of the apparatus and its method of use that have been described and/or illustrated in the accompanying drawings will be set forth in the following claims as inventive features, it is emphasized that the invention is not necessarily limited to those features and that it includes within its scope all of the parts of the apparatus and the steps in its method of use that have been described or illustrated both individually and in various combinations.
